Robusta coffee is not especially known for its hybrids, cultivars, and varietals. The quality of the coffee beverage is usually dependent on the proportion of both varieties in the blend, Arabica being a higher-value product (Alves et al., 2011). The coffee plant (Coffea sp., family Rubiaceae) is particularly abundant in tropical areas, and among the more than 90 different species, only Coffea arabica and Coffea canephora (also known as Coffea robusta) have major commercial importance and, respectively, account for 60% and 40% of the world’s coffee production (Farah and dos Santos, 2015). In fact, the quantity of acrylamide in roasted coffee is usually higher in Robusta than in Arabica coffees related to the higher amount of this precursor. Indian robusta coffees grown at altitudes above 1000 m tend to have clarity of flavors, with sweet acidic hues, enabling the branding of such coffees. GC×GC-FID analysis, using a Supelcowax-10×BPX-5 column set, provided the separation of nearly a thousand volatiles present in Arabica and Robusta coffees, and allowed the discrimination of both coffee varieties based on quantitative data (Mondello et al., 2004b). Several studies have compared the effectiveness of SPME fibers with different coatings (Freitas et al., 2001; Rocha et al., 2003), PDMS is the one commonly chosen for the characterization of the volatile composition of coffee varieties (Zambonin et al., 2005). Coffea canephora. Richard Morris. Previous studies have shown that torrefacto roasting masks the poor sensorial properties of Robusta coffee (Maeztu et al., 2001) and could be a fraudulent practice to hide the low-quality beans. C. arabica is native to the highlands of southwestern Ethiopia, whereas C. canephora is native to the lowland forests from Liberia east and south to Kenya and the Congo basin. There are no related plants for species Coffea canephora. While the tree itself is hardier than the arabica, making it easier and cheaper to cultivate, the brew itself has a distinctive stronger, harsher, grain-like taste. As a result of their high bitterness level the coffee beans cannot be used in every brew. In coffee. The higher levels of diketones, furfurals, and cyclic enolones (i.e., furaneol) in roasted Arabica coffees are a consequence of the higher abundance of sucrose in the initial green beans. The plant has an economic life of 20 - 80 years (average 50 years), with declining yields. Its plants are robust; however, the coffee beans are less favored because they tend to have a stronger, harsher taste than arabica beans. welwitschii (De Wild.) Coffea canephora Pierre [family RUBIACEAE] Coffea maclaudii A Chev. Coffee is an understory shrub or small tree native to tropical Africa. Altitudes above 1000 m produce hard beans, and the cup has clear flavor, besides brightness. Seed Availability. DNA molecular markers such as microsatellites or simple sequence repeats (SSRs) are powerful tools that could be utilized to quicken the improvement of marketable traits such as yield and cup quality. That said, it is also generally agreed that the resultant coffee from robusta is on an inferior quality than arabica. It is for this reason, whether it is arabica or robusta, the coffee farmer in India is trained and educated to take meticulous care at the various steps in processing to ensure the clarity of flavors and to prevent any off odors or off notes from developing in the coffee cup. Soares, ... M.Beatriz P.P. It was also well demonstrated that the same beverage quality could be obtained in agricultural production systems if environmental conditions required by those species are met. The word “coffee” may be a corruption of Kaffa, the province of Ethiopia where C. arabicaoriginated and may have been domesticated. Activated in 1958 by the Coffee Terminal Market Association of London, the robusta contract originally called for the delivery of “Uganda unwashed,” native grown robusta coffee. Reproduced from the series 'Plant Resources of South-East Asia', Vols 1-20 (1989-2000), by kind permission of the PROSEA Foundation, Bogor, Indonesia. C. canephora originates from equatorial rainforests at low to medium altitude between 250 and 1500 m (Davis et al., 2006). Cristina M.D. Unfortunately, with respect to the robusta species and its various forms, research has not been carried out on their individual sensory attributes, and also on the best practices for cultivation in different microclimates, which perhaps are the most important requirements to understand on how to improve the robusta species. With respect to the arabica species, research has been carried out on the cup quality of different arabica varietals such as Caturra, Catuai, Mundo Novo, Villa Sarchi, Sarchimor, Colombia VCR, Castillo, etc., with the cupping characteristics known to the coffee farmer, the coffee buyer, and the trader, resulting in not only the preparation of particular specialty coffees, but also single origin branded coffees for the market. It is not known for its quality brew so is usually used in blended coffees. An interesting observation in India has been that, just like for arabica coffees, the type of shade trees, under which robusta cultivation is being carried out, could have an effect on the cup quality. Coffea canephora Pierre ex A.Froehner var. Coffea species are shrubs or small trees native to tropical and southern Africa and tropical Asia. Coffee belongs to the Rubiaceae family, the genus Coffea with approximately 124 species. However, some discrepancies regarding the contents of aldehydes or pyrazines that may assist in discriminating between coffee varieties have been reported by different authors (Sanz et al., 2002; Zambonin et al., 2005). Robusta coffee is more productive yet less susceptible to disease, while Arabica coffee has a strong adaptation to different environments (Combes et al., 2013; Eric Nadelberg, ... Karsten Ranitzsch, in The Craft and Science of Coffee, 2017. Accordingly, higher amounts of amino acids in Robusta green beans result in higher final amounts of earthy, roasty, nutty smelling pyrazines. have been identified and quantified in blends of roasted C. arabica and C. robusta and significant differences in their contents have been observed (Sanz et al., 2002). After fermentation and washing, the coffee is dried carefully, either under the sun or with a combination of sunshine and mechanical dryers. C. canephor a is a diploid parent hybridized with Coffea eugenioides to produce Coffea arabica, an allotetraploid (Combes et al., 2000). As such, it is used quite widely in different breeding projects with the purpose of breeding into any new hybrids a higher resistance toward leaf rust and other diseases. Related Links. Last update on 2019-06-13: Now containing 11906 plants. Oliveira, in Processing and Impact on Active Components in Food, 2015. Coffee seeds were transported t… Coffea canephora, Coffea robusta Family: Rubiaceae Coffee Origin: Western Africa. Coffea arabica and Coffea robusta, the two main coffee species, have different value for consumers due to their sensorial properties and, therefore, different prices in the market. In the Ethiopian regions, the annual rainfall distribution is unimodal with a minimum from November to February and a maximum between May and September (Liljequist, 1986). A.Chev. C. canephora (2n=2x=22) is an allogamous diploid tree consisting of polymorphic populations. Coffea arabica (Arabica) and C. canephora (robusta) almost entirely dominate global coffee production. Additional water may also be required for the preparation of washed robusta, and the effluents from the pulping station would need to be carefully monitored and treated to preserve the water quality environment. This is a marked difference from the harvesting of arabica coffee, where the cherries have to be picked in a ripe red condition, as otherwise there could be an off note of “fermented” when picked in a darkish red condition. Parts Shown: Flower, Leaf Photo. These attributes are due to improper care taken during processing, which could be the result of low prices being offered in the market for the Robusta species. By and large, it was observed that the processing techniques followed on the farm have a bearing on its cup quality. (2004) continued these studies by analyzing the same coffee bean samples by GC×GC-ToF MS. Two sets of columns, polar/nonpolar (SolGel-WAX×BPX-5) and nonpolar/polar (BPX-5×BP-20) were tested; the first combination was more effective in the separation of coffee volatiles. The altitude at which robusta grows has an effect on the cup quality. It originates from western Africa. Although the Old Robusta or Peradeniya was introduced into India from Sri Lanka (formerly known as Ceylon) during the early 19th century, S.274 was the first robusta selection that was released by the Indian Coffee Research Station in the late 1940s. Interpreting Wetland Status. Prabhakaran Nair, in The Agronomy and Economy of Important Tree Crops of the Developing World, 2010. (1989) p 148, Pl. Coffea arabica 'Nana': This is a dwarf variety that only grows 12 inches tall making it ideal to cultivate indoors. In its areas of origin, C. canephora grows mainly on red soils (oxisols, ultisols) that are flat to gently sloping, well-drained, and acidic soils with low native fertility. C.canephora: Canephora is a genus of flowering plants in the Rubiaceae family. When compared to the vast territory covered by C. canephora, C. arabica appears much more limited. Other cultivars of this particular variety include Catimor, Sarchimor, Colombia, and Costa Rica 95. During drying, care should be taken to prevent under drying or over drying, as these could also affect the “cleanliness” of the robusta cup. Coffea canephora : Source: Rubiaceae of North America Update, database (version 2011) Acquired: 2011 : Notes: Updated for ITIS by the Flora of North America Expertise Network, in connection with an update for USDA PLANTS (2007-2010) Reference for: Coffea canephora : Source: The PLANTS Database, database (version 4.0.4) Acquired: 1996 : Notes: In addition to the washed method of processing, today, the “honey sundried”/“pulped natural” method of processing is also being utilized for the robusta species. However, Mondello et al. Coffea are shrubs or small trees, native to subtropical Africa and southern Asia. During fermentation, the coffee is constantly mixed to bring about uniform breakdown of the mucilage. Luigi Poisson, ... Thomas Hofmann, in The Craft and Science of Coffee, 2017. HS-SPME coupled to GC×GC has also been used to determine coffee volatile composition (Mondello et al., 2004b; Ryan et al., 2004; Cordero et al., 2008). With appropriate processing conditions, the coffee produced in native areas has outstanding sensory quality. Coffea canephora var. [family RUBIACEAE] Coffea robusta Linden. Coffee beans are actually seeds found inside the red berries that grow on the coffee plant. …coffee plant, Coffea arabica and C. canephora, supply almost all of the world’s consumption. Coffea canephora, commonly known as robusta coffee, is a species of coffee in the Rubiaceae family.Within its genus, C. canephora has the widest natural distribution which extends west to east from Guinea to Uganda, and north to south from Cameroon to Angola. Nevertheless, this may vary significantly due to cultivation practices and processing. SSRs are the molecular markers of choice in marker-assisted selection (MAS) of most crops because, they are widely found in the genome, are codominant, can be multiplexed and easily automated when compared to other marker systems such as AFLP (amplified fragment length polymorphism), RFLPs (restriction fragment length polymorphisms), or RADPs (random amplified DNA polymorphisms) (Aga et al., 2003; Leroy et al., 2005; Prakash et al., 2005). One resistant variety, Lempira, was widely planted in Honduras but lost its resistance to the disease in 2017, resulting in… Although there are some studies based on FA composition of Arabica and Robusta coffees (Alves et al., 2003; Romano et al., 2014), most of the GC analyses are focussed on the determination of the volatile compounds characteristic of coffee aroma. The ideal soils are light, deep, well drained, loamy, slightly acidic, and rich in humus and exchangeable bases, especially K. A.I. Well-washed robusta beans provide clean notes of strength and mild yet subtle flavors to the blend, thus providing wholesomeness to the coffee brewed either as espresso or as a filter drip coffee. It was observed that, the same strain grown at lower altitudes does not have this pronounced clarity of flavors and exhibits subdued flavor nuances. quillouensis, C. stenophylla, Congensis, and C. bukobensis are forms of different species, but popularly known as robusta. Because of the breeding with HDT, some resistance to coffee berry disease and leaf rust is present. Thus, the inherent quality characteristics of the plant strain are revealed in the cup and could be a major factor in determining the quality of the robusta as being “fine” or “commercial.”. Thus, “cleanliness” of the robusta cup can be affected at every stage of processing. In India, it was observed that, the washed robusta has a tastier profile than an unwashed robusta, though there are exceptions to this finding, with unwashed or natural robustas also being distinct, but complex in the cup. It is important that meticulous, organized, and careful processing steps are followed to preserve the intrinsic quality of the robusta beans and to avoid the off-tastes of commercial robustas, which could have woodiness, aged, stale, or rancid off-notes in the cup. Plant Citations. Coffea Canephora, also known as Coffea Robusta, is a hardier, more disease-resistant species than the more popular Coffea Arabica. Coffea canephora, commonly known as robusta coffee, is a species of coffee in the Rubiaceae family. Coffea arabica and Coffea canephora var. Charles Lambot, ... Alvaro Gaitán, in The Craft and Science of Coffee, 2017. Coffea robusta, generallynormally known as robusta coffee, is a vintage of coffee that has its origins in central together with western sub-Saharan Africa. The highest N absorption is mostly during the stage of flowering and continues into the stage of filling the coffee bean (ICCRI, 1999). Note: The antioxidant and caffeine content in Coffea Canephora is double than Coffea … It is a hardy plant, similar in climatic requirements to common coffee, but cannot be successfully grown where temperatures dip below 32F for any length of time.
